提出了一种由狭长RTD和矩形谐振腔组成的共振隧穿二极管太赫兹振荡器，并对其振荡特性进行了仿真分析。矩形空腔谐振器降低了振荡器的电感和电阻，而大面积RTD可以在高振荡频率下实现高输出功率。为了准确估计辐射功率，从三维电磁仿真中提取了详细的等效电路模型。根据分析，所提出的器件预计将在1 THz附近产生约2-3 mW的高输出功率。
A resonant-tunneling diode (RTD) terahertz oscillator composed of a long narrow RTD and a rectangular cavity resonator is proposed, and its oscillation characteristics are simulated and analyzed. The rectangular cavity resonator reduces both the oscillator inductance and resistance, while the large-area RTD enables high output power with a high oscillation frequency. To estimate the radiation power accurately, a detailed equivalent circuit model was extracted from 3D electromagnetic simulation. From the analysis, the proposed device is expected to produce a high output power of approximately 2-3 mW at around 1 THz.
